SPECIFICATION forming part of Letters Patent No. 756,836, dated April 12, 1904.

Application filed November 10, 1903. Serial No. 180,513. (No model.)

To all whom, it may concern:

Be it known that LOMAR CLARKE DE SELMS, a citizen of the United States, residing at At tica, in the county of Fountain and State of Indiana, have invented certain new and useful Improvements in Instruction-Sheets, of which the following is a specification.

This invention relates to improvements in means for giving instruction in person or by correspondence methods; and the object is to place before the student samples of the article under discussion in a dismembered condition with all of the parts regularly and systematically arranged and appropriately labeled, also to instruct in the manufacture of mechanical devices by placing before him samples of the work as it appears at various successive stages from start to finish.

The object of the invention also is to provide a convenient medium for the presentation of the above subject-matter and to provide same in a form capable of subdivision, so that parts may be placed before the student when it is not desirable to submit the whole.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective'view of my invention in closed condition; Fig. 2, a section on the line 2 2 of Fig. 1; Fig. 3, a front view of one of the subdivisions or sheets of my improved device, showing the disassembled parts of a watch; Fig. 4, a like view of another sheet, showing the successive operations in the manufacture of a Watch-staff and the tools employed; andFig. 5, a perspective view of one of the spacing-strips used for separating the sheets shown in Figs. 3 and 4.

Like characters of reference indicate like parts throughout the several views of the drawings.

The sheets 6 are of any suitable strong and durable material, such as tag-board, sheet metal, leather, or the like. They are marked oif by means of the longitudinal lines 7 and 8 into three longitudinal divisions, of which the one 9, at the left has the perforations 1O 10, through which a cord 11 is passed for the purpose of binding the several sheets together.

The middle division 12 is to receive the objects which are to be displayed and the outer right hand column the names of the objects displayed in column 12, together with such instructions or information as may be deemed essential for record there.

The objects displayed in column 12 of Fig. 3 are the disassembled parts of a modern watch and are arranged in the order in which an experienced watchmaker would remove the parts. In this way the novice is informed as to the correct method of procedure in taking a watch apart, and the parts are named and positively identified by the physical produc tion of the parts in the spaces directly opposite their nomenclature. For greater eertainty 1 separate the middle and right columns by means of the horizontal lines 13 into spaces, so that the article may be always placed in the appropriate division opposite its name.

The sheets will be numbered, as 1 and 7 at the upper right corner. It will be understood that as many sheets as are required will be used for showing all of the parts of a Watch or other article if they exceed in number the capacity of a single sheet, as they do in this example.

After the disassembling of the watch is shown the making of the different parts is illustrated step by step after the manner illustrated in Fig. 4. Here the making of the staff, which in actual use is very small in size, as shown by the illustration at the bottom of column 12, is shown on a greatly-magnified scale, starting with the blank 14. The shape of the hub is next shown, then the seat for the balance, and following in succession are models showing the seat for the hair-spring collet, the top pivot, the oil-cut, and then the staff complete. The tools used in the making of the staff are illustrated at the top of the sheet. After the student has familiarized himself with the proper construction on a magnified scale he can intelligently take up the making of the diminutive actual article.

Where the parts to be secured to the sheet are large enough to admit of it, they may be secured by thread stitches 15 or other means; but where the size of the article and its shape prohibits the use of stitches they are embedded in a drop of transparent glue 16. Where wheels have long arbors, the inner ends of the latter are pushed through the sheet, as shown as the sheets and have perforations which regcles to serve as object-lessons are ister with those of the sheets, so that the strips and sheets will all be held and bound together by means of the cord 11.

Accompanying the sheets bearing the arti-' preferably printed sheets 19, containing detailed directions and instructions which the limits of sheets 6 make it impractical of embodiment thereon. The sheets -19 and sheets 6 are bound together with cord 11 in the manner shown in Figs. 1 and 2, which permits of the separation and removal of such sheets as are not desired to be placed in the hands of a particular student at that time.

Obviously, if desired, the instruction-sheets 19 may be used separately from the sheets 6.

Having thus fully described myfinvention, what I claim as new, and wish to secure by Letters-Patent, is

1. An instruction-sheet having a series of bodies physically illustrating a single composite whole arranged in a progressive order, worded, information accompanying each of 4 said bodies printed on the sheet and lines dividing the sheet into separate spaces for each body and description.

2. An instruction-sheet having a series of bodies physically illustrating a single compos-- ite whole arranged in a progressive order,

worded information accompanying each of said bodies at the right-hand side thereof on said sheet, a printed line separating the column of bodies from the column of in formation and cross-lines separating each body and its description from those above and below.

3. An instruction-sheet divided by lines into three longitudinal sections or columns the middle and right-hand columns divided by transverse lines into sections, bodies secured in the sections of the middle column and information relative to each body printed in the horizontal section opposite it.

4B. A plurality of instruction-sheets each having a series of bodies physically illustratmg a single composite whole arranged in a progressive order, wordedinformation accompanying each of said bodies and printed on said sheet, perforations through the left margins of the sheets, perforated spacing-strips laid between the perforated edges of the adjacent sheets and a bonding-cord passed through the perforations and having their ends removably secured together.

5. A plurality of instruction sheets each having bodies secured thereto and descriptions of said bodies thereon, said sheets having marginal perforations, perforated spacing-strips between the sheets and a cord binding the parts together.
